EFNEETKL/RTBAL/ER Patented Sept. 14, 1943 GUIDE RAISING DEVICE Ernest Kurt Bauer, Meadville, Pa., assignor to American Viscose Corporation, Wilmington, Del., a corporation of Delaware iApplication September 5, 1941, Serial No. 409,650 r 2 Claims.

This invention relates to improvements in apparatus for winding a yarn package. More particularly, the invention relates to improvements in apparatus for winding a yarn package whereby a yarn package may be obtained in which the yarn has substantially the same physical characteristics throughout.

Where a yarn package is formed by the ordinary winding means, some parts of the yarn are subjected to greater strain than others with the result that the physical characteristics of the yarn, especially the dyeing properties, are not uniform.

Theprincipal object of the invention is to provide improvements in apparatus for winding a yarn package in which the yarn has substantially uniform physical characteristics throughout.

Another object of the invention is to provide improvements in apparatus for winding a yarn package having means for adjusting the tension on the yarn being delivered to the package.

A further object of the invention is to provide improvements in apparatus for winding 2. yarn package comprising a spinning cap having means for increasing the tension on the yarn bein delivered to the collecting bobbin.

is fixed to the'cam and engages the rack bar 18 pivotally attached to thearm 19 of a bell ing bobbin. As the winding operation progresses.

Other objects and advantages of the invention will be apparent from the following description and accompanying drawing.

In the drawing Figure 1 is a side elevational view of a preferred embodiment of the invention.

Figure 2 is a front elevational viewof the embodiment of the invention shown in'Figur 1.

Figure 3 is a perspective view of the cam and clutch means shown in Figures 1 and 2.

The invention broadly comprises means for raising th guide directing yarn, to the spinning cap during the spinning operation to increase the size of the balloon and the tension on the yarn.

In the drawing reference character I indicates a ballooning yarn passing from the guide 2 to the spinning cap 3. The guide 2 is carried by the member 4 which is mounted to slide vertically in the guide brackets 5 and 6 and carries'at its lower end the cam following roller 1 A cam member 8 is mounted to freely revolve on the driven shaft 9 supported by suitable bearings and is positioned to engage the cam roller 1. The cam member is provided with means for coupling it to the hub I0 which is fixed to the shaft 9 so that the cam will rotate with the hub. The coupling means comprises the brake band I l which passes around a portion of the hub and is fastened at one end to the pin .12 mounted on the cam and at .the

other end to the threaded rod l3 which extends through the lug portion on the cam. The friction of the brake band on the hub may be adjusted by the nut I6 which acts on the spring IS. A ratchet wheel I! concentric with th shaft 8 the cam rotates in the direction shown by the arrow in Figure 1 which raises the cam roller I and the guide means 2. A the guide means 2 is raised, the size of the balloon of th yarn increases which in turn increases the tension on the yarn being delivered to the collecting bobbin.

The teeth on the ratchet wheel: and the rack barare so arranged that the ratchet wheel may rotate with the cam without actuating th rack bar. At

the completion of the winding operation, the a cam is in the position shown in Figure 1. The cam may then be returned to its starting position by depressing the pedal 20 which actuates the rack bar to rotate the ratchet wheel and the cam to its starting position. i

In order to insure a fixed starting position, the cam is provided with a laterally extending pin 22 and the arm IQ of the bell crank is provided with a laterally extending lug 23. On depressin the pedal 20 the cam revolves until the pin 22 strikes the lug 23. The pedal is then raised to its operative position by the spring member 2| and the lug is moved out of the path of the pin.

While a preferred embodiment of the invention has been shown, it is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined by the appended claims.

What I claim is:

1. Apparatus for winding a yarn package comprising a spinning cap, guide means for directing yarn to the spinning cap, means for raising the guide means above the spinning cap during the winding operation toincrease thetension on the yarn being delivered to the spinning cap and means including ratchet means for returning the guide means to its lower position. v

2. Apparatus for winding a yarn package com- I prising a spinning can. uide means for directing yarn to the spinning cap, means for raising.
